In the manufacture of tools of this` class,y

difficulty has been experienced in preventing the socket walls fromopening upr orfspread# ing when a downward pressure is exerted on thehandle of the shovel.

The object of my present invention is to provide means cooperating withthe reinforcing blade and socket rivet to resist the downward thrusttending to separate or open the wallsofthe socket and transmit suchthrust to the ends of the rivet, the result being that the pressure onthe handlewill tend to draw the walls of the socket together rather thanseparate them.l

shovel socket and the 'rivets for securing the band and handle sectionstogether.

In the drawing, 2, represents the blade of the shovel having alongitudinal extension tatone end that is folded downwardly by suitablemeans to form a handle-receiving socket having walls 3 and 4. Thehandle, composed preferably of separable wood sections 5, is fitted intothe socket and has a reinforcing blade 6 between the sections and whenthe parts are assembled the socket walls, wood sections and reinforcingblade are firmly secured together by means of suitable rivets 7countersunk Vin the walls of the socket and similar rivets 8 which passthrough the secy Y tions of the handle outside the socket and In theaccompanying drawings forming have their ends countersunk in the woodportions thereof. On the end of the handle a suitable grip 9 isprovided.

In shovels, spades, or scoops of this type` the folded longitudinaledges of the socket walls are not secured together but are separated bya narrow gap or space and when downward pressureis applied to the handlein the use of the tool, these walls will be separated, the pressure onthe reinforcing blade tending to forcethem apart and open up the socketand destroy the usefulness of the tool. To obviate this diiiculty in theuse of a shovel of this type, I propose to unite the longitudinal edgesof the socket by suitable means such as welding, as indicated at 10 inFigures 2 and 4, the welding operation forming the final step in themanufacture of the shovel and causing the edges of the socket to besecurely bound together and united as in one piece.

vIn Figure 3, I have shown a modification which consists in providingtongues 11 dove tail in form, fitting into correspondingly shaped socket12 in the edges of the socket walls 3 and 4, t-he tongues being insertedinto the sockets during the folding operation and becoming lockedtherein against any movement which would tend to separateor spread thesocket walls.

In Figures 5 and 6, I have shown another modification which consists informing a band 13 of suitable material, preferably a thin gage of metal,folded to lit snugly against the surface of the wood handle sectionwithin the socket, the ends of the band preferably being separated asindicated at 14 to allow its convenient placing on the handle sectionand permit it to accommodate itself to slight variations in the sizeofthe handle sect-ion.

Holes 15 are provided in the band to receive the endslof'the rivet 7".Evidently downward pressure on the reinforcing blade 6 will be absorbedby the band and transmitted to the ends of the rivet and the tendency ofthe socket walls to open up or separate under vsuch pressure will beeliminated.

The band 13, may be closed if ireferred, and when made in this way, ispre erably tapered to fit the taper of the handle and canthen be drivenon to make a snug lit. Y s,... Y .c

In Iligure i I have shown a modification of therinforcing means whichconsists 1n pro? vidingacontinuous ring 13a' which may bel made bycutting ofi1 a section of tubing of suitable size and formedto fit theend ofthe vhandle and bind thev sections andv the' reinforcing bladetogether. Rivet' holes 15a are provided in the ring to receive the endsof the rivet inserted through the socket walls and` 'the reinforcingblade. This ring will` bridge the openingbetween theedges ofthel socketwalls and will effectually yprevent the separation of the wallsresulting from downward a pressure on the handle and the reinforcingblade. In this way, I provide a very simple inexpensive 'means forreinforcing a hollow- .back shovel ata point which has provedstructurally weak in the use of the tool.

Iii-Figure 9, I have shown a modification in the socket. 'Instead ofhaving the Y edges thereof terminate on the under side of thehollow-back, I provide extensions 16v thereonwhich` arey folded inwardlyin parallel relation andv adapted to receive the'reinforcing` bladebetween them and'having holes'vfor the rivets which bind the walls ofthe' socket and the reinforcing blade together'. These `in wardly turnededges havingzbearings on the middle'portion of the rivets will preventthe socket walls from separating andthe handley beconiing'loose intheshovel blade. A shovel,l

' spade, or scoop madeV inthis way will'be extremely strong rand durableand capable' withstanding any pressure to which an article of this kindmay' be subjected. It will be understood of 'course that instead offolding the walls of the socketdownwardly they may be turned upwardly sothat the gap be-v tween the walls will be on the upper side of thehollow-back instead ofr on'.v the lower side. This, however, will makenodifi'erence in the use of my' 'invention as similar means or methodsof reinforcing or binding the wallsof the socket together maybe employedwhether the# socket is folded downwardly or upwardly in the constructionof the shovel.` Y

preferably to the opposite side of the band. These inwardly turned edgesor flanges I will indicate by reference numeral 13"'. The handlesections are inserted into the openings in the band in assembling andthe reinforcing blade 6 is dropped into the recess formed by theseparation or drawingl apart of: the; sec tions of the band. 'When thishas been done, the sections are closed or drawn together as indicatedinFigure 1- 1 and secured byfsnitj able means such as a rivet-18d.

I prefer to use rivets for securing the parts of the shovel together.The rivetsS and 13 are inserted when the sections and band are assembledand-.before placing them in the socket of the shovel.` The rivetpreferablyv passesl through thev lhandle sectionsjand the reinforcingblade alone while the rivet 13' passes through the handlesections,'theblade and the reinforcing band." VAfter the assem bled parts areinert'ed intoV the socket they are Vall securedtogether by theinsertionof the.

rivet 7 fitting openings inthe walls of the socket and passingthro-ug'hthe handle, the reinforcing blade and the band.
